CONTROLLER vHANDLE.

Application filed July 25, 1923.

T all whom it may concern.

Be it known that I, THOMAS I. MohRIsH, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Controller Handles, of which the following is a specification.

This invention relates to improvements in handles for use in connection with various control stems, particularly those employed in controlling motors or air brakes. However, the handle is adapted for use generally where a detachable handle is desirable, and one wherein the wear occasioned between the stem and the aw is to be taken up to ensure a tight connection between the parts.

One of the objects of this invention is to provide an adjustable controller handle wherein the parts are substantially duplicates and are hinged at one end enabling the jaw ends to be" brought into contact without the stems contacting enabling the jaw faces to be trimmed should for any reason the inner surface of the jaw depression become enlarged and require that the surface be brought closer together to engage a stem of given size.

Another object is to provide an improved construction of handle for attachment to the jaw stems, to provide a quick adjustment for moving the jaws relative to each other, and to generally improve jaw constructions of the adjustable type.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion,

size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein Fig. 1 is a View in plan of the preferred embodiment of my invention illustrating part of the handle broken away disclosing the threaded cylindrical surface of one of the jaw stems.

Fig. 2 is a view in side elevation.

Serial No. 653,716.

Fig. 3 is a sectional view taken on line 38 of Fig. 4:.

Fig. at is a transverse sectional view on line -i4 of Fig. 1, and

Fig. 5 is a sectional view of the adjusting connection on line 5-5 of Fig. 1.

In the drawings, the numeral 1 indicates the valve stem or controller stem to be operated, and the stem is received in a hole 2 formed by the carrying out of a figure made possible by the co-operation of the depressions 4 in the opposing aw faces. The jaw faces areadapted to register with their adjacent surfaces 5 in contact, and from their inner ends extend the stems 6, the inner edges 7 of which are adapted to lie in spaced relation when the portions 5 of the jaw are in contact.

The stems 6 are of corresponding length, and at its end one of the stems terminates in a cylindrical portion 8, one part of which projects beyond the inner face 7 of its associated stem, as at 9. The cylindrical part 8 is inwardly slotted,preferably on a horizontal plane, as at 10, to receive the relatively flat hinge portion 11 formed at the corresponding end of the opposing stem 6. A pin 12 passes through said portions 8 and 11 and forms a hinge joint connection for co-operating ends of the stem 6. To the eXteriorly threaded cylindrical portion 8 is attached a conventional operating handle 13 mounting a threaded ferrule 14 which engages the cylindrical portion 8. One of the stems 6 mounts a threaded bolt or stud 15, the threaded end of which projects through an aperture 16, in the opposing stem 6, permitting a relative swinging of the stems on their hinge connection, and a winged nut 17 associated with the end of the bolt 15 is adapted for adjustment to draw the jaws into engaging relation around the stem 1. A coiled spring 18 received at its ends in depressions 19 in opposite faces of the stems 6 between the jaws and hinge connections separates the jaws on the outward threading of the nut 17 on its bolt 16.

It will be apparent that the engaging surfaces 5 at the jaw end of the present invention could be cut down or built up to'fit the recesses 4 to engage the walls of a stem of any desired size without in any manner re,- quiring work to be done on opposing faces of the stem 6. It will also be apparent that the handle 13 may be removed from the on its detachment.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent of the United Statesisz- 1. A controller handle comprising a pair of jaws formed with a hole to fit on an air brake valve stem or the like, stem sections extending from the jaws and hinged together, the end of one stem section being inwardly slotted to receive the other and having a cylindrical threaded periphery for receiving a handle, a threaded bolt carried by one stem and extending through the other, a nut on the bolt for adjustment to draw the jaws together. and a spring for normally separating the jaws.

2. A controller handle comprising a pair of jaws formed with a hole to fit over an air brake valve stem or the like, stem sections extending from the jaws and hinged 7 together at their end, a handle secured to the stem sections, a threaded bolt carried by one stem and extending "through the other, a member for adjustment on the bolt to draw the jaws together, and a spring for normally separating the jaws.

3. A controller handle comprising a pair of complementary jaws-hinged together at one end and their opposite ends provided with cooperating depressions forming a hole for the reception of an air brake valve stem or the like, a spring for normally separating the ends of the jaws, and an adjustable member for acting against the spring for drawing the jaw together, the portion of the jaws between the hinged connection.

and depressions lying in spaced relation on the contacting of the jaw portions forming the valve stem receiving hole.

4:. A controller handle comprising a pair of complementary jaws hinged together at one end, and the opposite ends provided with co-operating depressions forming a hole for the reception of an air brake valve stem Or the like, a spring for normally separating the'free ends of the jaws, an adjustable member for acting against the spring for drawing the jaws together, and a handle threaded to the hinged end of the jaws said handle threadably engaging but one jaw.

In testimony whereof I have signed my name to this specification.
